M42 lenses readily adapt to EOS but K mount is a different story altogether. Using K mount lenses on EOS bodies other than the EF-S digital bodies (Digital Rebels, 20D-50D) requires non-reversible physical modification of the lens in question. The guard for the aperture stop-down lever must be removed (permanent mod) and the stop-down lever itself must either be removed or cut down (may be reversible depending on lens).
Infinity focus is achievable. Aperture Priority and Manual modes work with TTL flash but metering may not be reliable depending on body (I'm not sure if the 500n has accurate stop-down metering). You lose everything else (AF, full-aperture metering VF display of aperture, all exposure modes other than Av and M) -Adam On Mon, Apr 13, 2009 at 8:10 PM, Luiz Felipe <[email protected]> wrote: > Since I'm stuck for a while with a EOS 500n, I'm wondering about those > adapters.
